Lately I've been reading more and more about excellent restaurants in Germany that are giving up because it's no longer profitable and they can't find staff. That's sad and also strange, because it obviously worked n the past.
I think it's been said that the cost mechanics of restaurants- providing food at a price that's worth it versus making it yourself - relies on either mechanical efficiencies ("restaurant" can make food with less labor than at home, ie- fast food) or cheap labor. As the salaries of the people making the food approaches the income of the customers the restaurant model tapers off in attractiveness and ultimately fails. Of course there is space "around the edges", underpaid people, ethnic food made by immigrants, gourmet food bought only by the wealthy, but the "middle", good native food at reasonable prices, would disappear. Granted this is all by degrees and maybe there's a steady state in-between, but the reliance on income inequality can be seen simply when one can say, "my time is worth so much that I can justify paying someone else to cook me food".
EDIT- just so this doesn't turn political, I'm NOT trying to advocate for or against any current topic, simply proffering one analysis of the mechanics of the costs of the restaurant business vs home cooking, to be up/down voted, analyzed, commented on, etc. by us here.
